What we've built and what we're building.
A headless component library for React — unstyled by default, accessible out of the box. Bring your own styles, own your design system.

A focused space for writing, sharing, and learning together. Less clutter than a wiki. More collaborative than a note app.

AI code review that understands your codebase. Surfaces real issues — not surface-level noise. Connects to GitHub and your IDE.

Behind the studio
Pushpendra Singh
I build Ninexgo after hours — developer tools, platforms, and internet products I wish existed. Designing and building since 2011 — from graphic design to leading frontend at scale — all of it channelled into smaller, sharper things built with clean architecture, thoughtful design systems, and zero shortcuts.
Say hi on X →How we build
Every product starts as a design problem. We obsess over the experience before writing a line of implementation.
For developer tools, the API is the UI. Every interface — visual or programmatic — is a design decision. If it's confusing, it's broken.
We'd rather do one thing exceptionally well than ship ten things mediocrely. Smaller scope means every edge case gets attention.
We don't optimize for launch day. We optimize for the version of the product six months after launch — when the hype is gone.
Now building
→Sentinel — GitHub integration
Building the core review engine and GitHub app. IDE extension in parallel.
→Anchor UI — Adding more components
Locking the component API. Accessibility audit in progress.
→Open source utilities
Internal tools that power our products. Planning to release separately.

Work together
The studio occasionally takes on focused engagements — developer tools, design systems, and platform work.
